THE SD SERIES COLLECTION

Conquer Any Terrain With The Mule SD
Born from the heritage of Bakcou’s flagship Mule, the Mule SD takes everything riders love about the original workhorse and supercharges it. At its heart is Bafang’s ultra‑powerful M620 mid‑drive motor (750/1000 W), often called the “diesel engine” of e‑bike motors, which churns out up to 160 Nm of torque and 1 500 W peak power. This torque‑rich motor, paired with an 11‑speed SRAM NX drivetrain and removable thumb throttle, delivers the hill‑climbing muscle hunters and off‑road riders need. A 52 V 20 Ah lithium‑ion battery powers the system, and Bakcou’s modular rack lets riders add an extra 15 Ah or 20 Ah battery to double the range—up to 40 Ah total—eliminating range anxiety on long hunts and multi‑day expeditions.

Built around an aircraft‑grade 6061‑aluminum frame with a patented rear rack, the Mule SD balances strength and agility. Its inverted 120 mm air‑fork suspension and shock‑absorbing seat post smooth out rocky trails and washboarded dirt roads, while 24‑inch or 26‑inch fat tires (CST or Maxxis Minion) provide unrivalled traction on mud, sand and snow. Four‑piston Tektro HD E725 hydraulic disc brakes deliver confident stopping power, and wide, skid‑proof pedals offer secure footing even with heavy boots. An integrated stem display with Bakcou’s On‑Demand Program (ODP) lets riders choose between Class 1, Class 2, Class 3 or unlimited modes, while Bakcou Connect technology (free the first year) gives remote security, tracking and diagnostic capability via smartphone.

FAQs about the SD Models

The SD line covers a wide range of riding styles:

  • Mule SD – Built for steep mountain trails and technical backcountry hunting. Its mid‑drive motor and 4‑piston brakes make it ideal for climbing, descending and towing gear in rugged terrain.

  • Kodiak SD AWD – Tailored to snow, mud and sand, this all‑wheel‑drive e‑bike delivers unmatched traction on loose surfaces. It’s perfect for hunters who traverse beaches, marshes or winter landscapes.

  • Flatlander SD – Designed for flatlands and rolling hills. Its dual‑speed hub motor and low‑step frame make it a comfortable choice for fields, farmlands and gravel roads.

Whether you need a trail‑riding electric mountain bike or a flatland cruiser, there’s an SD model to match your terrain.

Our Super Duty line uses powerful 52 V lithium‑ion batteries designed for long‑range hunting and trail riding. Each SD bike comes with a 20 Ah integrated battery, and the rear rack accepts an additional 15 Ah or 20 Ah battery—giving you up to 40 Ah of capacity. Range depends on rider weight, terrain and assist level, but these capacities put our Super Duty bikes among the longest‑ranged fat‑tire electric bikes on the market.

All SD models feature torque‑rich motors designed to tackle steep climbs and haul heavy loads:

  • Mule SD – Powered by the Bafang Ultra M620 mid‑drive motor adjustable between 750 W (Class 1/2/3) and 1 000 W (unlimited). It churns out up to 160 Nm of torque, earning it the nickname “diesel engine of ebike motors”.

  • Kodiak SD AWD – Uses two 750 W hub motors (front and rear). Each hub produces 85 Nm of torque, allowing you to engage front‑wheel drive, rear‑wheel drive or all‑wheel drive for incredible traction.

  • Flatlander SD – Equipped with a 750 W dual‑speed Bafang hub motor with 85 Nm of torque. The sealed gearing eliminates the derailleur, making it ideal for low‑maintenance use.

Every SD bike includes our On‑Demand Program (ODP) display, which lets you select Class 1, Class 2, Class 3 or unlimited mode to comply with local ebike laws.

Mule SD: Our flagship hunting e‑bike includes Bakcou Connect free for the first year. This smartphone‑enabled system lets you track your fat‑tire e‑bike, lock or unlock it remotely and monitor the battery state of charge—features that add security and peace of mind when you’re deep in the backcountry.

Kodiak SD AWD & Flatlander SD: Both bikes are Bakcou Connect‑ready, but require you purchase the package at checkout to enable GPS tracking and remote lock/unlock. Without the subscription, the bikes operate normally but won’t provide the connected‑bike features. After the first year, Bakcou Connect requires a low annual fee to continue these services.

Our Super Duty bikes are engineered for heavy loads. Each model can comfortably carry up to about 300 pounds of rider and gear, and the integrated racks are designed to support trailers and game carts. The Mule SD and Kodiak SD AWD feature high‑torque motors and reinforced rear racks, making them especially well‑suited for towing cargo. The Flatlander SD is lighter and optimized for moderate loads but still capable of hauling camping gear or harvests on its sturdy rack. Combined with the available hitch attachments, these e‑bikes make an excellent choice for hunters and outdoor enthusiasts who need to transport gear into remote areas.

Bakcou stands behind every Super Duty fat‑tire electric bike we build. All SD models come with a 30‑day return policy—return or exchange your e‑bike within 30 days of delivery if it’s in new condition (under 10 miles and no wear). A 15% restocking fee and $300 return shipping apply, and you must get authorization first. We also provide a lifetime warranty on the frame for the original owner and a two‑year limited manufacturer warranty covering core components such as the mid‑drive motor or hub motor, lithium‑ion battery, suspension, drivetrain and electronics. To ensure coverage, register your bike within 45 days of purchase and note that damage from misuse or normal wear is not covered. This robust warranty program reflects our commitment to reliable, heavy‑duty e‑bikes for hunting and backcountry adventure.

UNSTOPPABLE
ALL-TERRAIN FREEDOM.
